PORTER DODGE, OF PERKINSVILLE, VERMONT.

IMPROVED SOAP-STONE STOVE.

Specification forming part of Letters Patent No. 46,455, dated February21, 1865.

To all whom it may concern:

Be it known that I, PORTER DODGE, of Perkinsville, county of Windsor,and State of Vermont, have invented certain new and useful Improvementsin Soapstone Stoves; and I do hereby declare thatthe following is afull, clear, and exact description of the construction and operationofthe same, reference being had to the accompanying drawings, in which-Figure 1 represents a longitudinal vertical Fig. 2 represents a verticalcross-section, and Fig. 3 a hoiizontal section through the same. Fig. 4repreents a perspective view ofthe iion bottom plate and skeleton frameof the stove.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents the bottom plate of the stove, which is made of iron. Brepresents its sides. They are made of soapstone, and are'held in theirplaces by means of the iron skeleton frame. (Represented in aperspective view at Fig. 4.) The said skeleton frame consists i1 thefour corner pieces, O, the lower ends of which are inserted in orotherwise secured to the bottom plate A. They are held in theirpositions by means of the top piece D, which is secured to the cornerpieces by means of projections b of the latter extending into holes inthe top fra-me D. The latter also serves by means'of its horizontal danges d to support the top plate, E, of the stove, which is also ofsoapstone. The ends of each of the soapstone slabs are slipped intosuitable grooves in the corner piece of the skeleton frame, and they arethus held securely in their positions.

When the stove is of an oblong rectangular shape, as represented in thedrawings, I use on each of the longer sides a middle piece, G, providedwith suitable grooves for the reception of the soapstone slabs, and Iamthus enabled to use comparatively small slabs for the large sides of thestove, which are thus not as liable to break or crack as the largesizes.

F represents the outer iron work of the stove, Vwhich serves to protectthe outside of They may be made at or concave, as represented at Fig. 3,and they also are held in their positions by means of the corner pieces,O, which are for this purpose provided with extra grooves, into whichthe ends of the sides F are slipped.

To apply the stove-pipe in a substantial and neat manner to the side ofthe stove, I provide the central piece, G, of one of. the longer sideswith a pipe-thimble, H, which is cast thereto, as represented on thedrawings, said thimble being provided with circular flanges g, againstwhich the soapstone slab is neatly fitted. I make the sides ofthethimble H of sufficient thickness to permit the formation of agroove, o, on its end, by which I am enabled to apply different sizes ofpipes to it. One size can be inserted into said groove and the other canl e applied to the outside of the thimble H.

It is well known that the sides of a stove become heated to a higherdegree at or near their centers than near the corners. When soapstone isused for the sides, the uneven expansion of the parts cause, them tobreak and render the stove unfit for use. This difficulty l avoid byusing inner linings or pieces of v soapstone, which I apply in separateframes to the central part ot' each ot' the sides of the stove. Forythis purpose I use iron frames K of the shape represented on thedrawings, the lower ends of which are inserted in or otherwise securedto the bottom plate, A, and in these frames I insert the innerprotecting-lining or soapstone, L. When thus applied, the central partof each side is protected from becoming heated in a higher degree thanthe ends, and thus uneven expansion and breakage are avoided.

M represents the door of the stove, and O the door ofthe outerperforated side.

N represents the top part of the stove, which is made of open iron work,and which s ipports the topl plate, P, of soapstone.

From the above description it will be seen that the sides and top of thestove, which are of soapstone, are secured in a substantial and neatmanner to the iron skeleton frame, the whole presenting a soapstonestove of elegant shape and design, and in which the sides are not liableto breakage by reason of uneven expansion.

Having thus fully described the nature of my invention, what I claimherein as new, and desire to secure by Letters Patent, is-

1. Constructing and arranging the corner pieces, C, of the iron skeletonframe of a stove so that they hold the soapstone slabs and the outeropen iron-Work F, substantially in the manner described.

.2. In combination with the corner piece, C,

secured to' the bottom of Jche stove, the top piece D, for the purposeof holding both the corner pieces and the top slab, E, of stove,substantially in the manner described.

3. The combination and arrangement of the inner linings L with lcheouter slabs B, when constructed and applied substantially as and for thepurposes described.

4. The combination and arrangement ofthe iron skeleton frame with thesoapstone sides B and top E, inner linings, L, outer open iron Work F,and stove-pipe attachment, substantially as and for the purposes setforth.
